Okarche, Oklahoma April Weather

Precipitation was impressive through the first quarter of 2017, and that trend continued in April.  A total of 9.67 inches of rain fell during the month which was 295 percent of average.  This was the second greatest April total on record and it featured daily rains of 3.65 inches on the 29th, and 4.30 inches on the 21st.  The 3.65 inches on the 29th would have set a monthly record had it not been for the 4.30 inches which occurred eight days earlier.  4.30 inches is the 4th most ever in a calendar day and one of only six days where rainfall has reached four inches during 36 years of record keeping.  3.65 is the 10th most in a calendar day.  The January to April total of 19.65 inches is the most on record.

Three days saw hail, and hail to the size of golfballs was observed during the early morning hours of the 29th.

At the end of April 29th, the April temperature stood just slightly above average.  A very cool day on the 30th brought the average monthly temperature of 59.9 degrees in at a 1/2 of a degree below average.  This was the first month of the year where the monthly temperature was below average.

Okarche, Oklahoma Last Freeze

We’ve had some cool weather during the last half of April and the start of May, with even one May record low temperature tied.  It does not appear that any more significant cold weather will be visiting the state and we can officially consider the last freeze of the season to be March 15th, when the low reached 26 degrees.

This was just over three weeks earlier than the average last freeze of April 6th.  It was so early in fact, that it has now changed the date of average last freeze to April 5th.   Climate change?

The last freeze of March 15th is the 5th earliest last freeze and just six days off the record of March 9th.

We are now in the clear for the growing season.  The average first freeze in Okarche is on October 31st, and the record first freeze is October 7th.
